Answer:
-√2
Step-by-step explanation:
x² - 2x = 8 Apply the square root to both sides
√x² - 2x = √8 Divide both sides by -2
x = -√2
<u><em>Extra info:</em></u>
√8 = 2√2 = 2.828427125
-√2 = -1.414213562
18/5 = x/100
1800 = 5x
----- -----
5 5
360 = x
You can use proportion to solve your equation to figure out the x value so you have corresponding ratios
Answer: -3x+1 and y column will have the same answers because y = -3x+1
<u>-3x+1</u>
-3(-2)+1 = 6+1 = 7
-3(-1)+1 = 3+1 = 4
-3(0)+1 = 0+1 = 1
-3(1)+1 = -3+1 = -2
-3(2)+1 = -6+1 = -5
<u>(x, y)</u>
(-2, 7)
(-1, 4)
(0, 1)
(1, -2)
(2, -5)

Negative slope
Slope = -3
I'm not sure but if I'm right I think it's 5.3 pounds would be 12.5 which is the closest to 12.64.
Again, not sure. If you know the right answer, I'd like to know it please. :]
